High-level Property Specification Language

Project description


HPL - The High-Level Property Specification Language

HPL is a minimalistic specification language tailored for behavioural properties of message-based systems. Although it might be useful in other contexts, it was designed with the message-passing system of the Robot Operating System in mind. Since properties are message-based, the same language can be used to specify both individual nodes and full applications.

HPL was developed to be an integral part of the HAROS framework. HAROS is capable of defining and extracting architectural models of ROS systems (the ROS Computation Graph). Such models are, inherently, mostly concerned with the structure of the analysed system. This language is meant to annotate the architectural models, complementing them with behavioural information.

What Is In The Box

This repository contains a Python package, and the respective source code, to parse HPL specifications and convert them into Abstract Syntax Trees (AST).

Syntax, Semantics and Use Cases

Check the documentation.


To install this package, make sure that you have Python 2.7 or greater. Simply run the command:

pip install hpl-specs
